The Commercial Vehicle Model is a 3-step travel model that predicts non-Home-based trips made by commercial vehicles.
This model uses the same TAZ employment data as the Home-based models, plus trip generation and attraction rates and gravity model friction factors specifically for commercial vehicles. The model input files and their formats are described on the Model Inputs page.
In order to run the model, input files should be checked and the following entries in settings.csv should be confirmed:
- runCommercialVehicleModel should be set to TRUE.
- maxIter_Commercial should be set to the desired number of iterations. The default in the JEMnR documentation is 5 iterations and CALM currently runs 20 iterations.
- CVMFactor is a single factor used to multiply CVM trips.
The model runs as part of the normal JEMnR model flow.
The Commercial Vehicle Model is documented in the JEMnR Model Documentation in Appendix E on page 149.
